' FODDER-CUTTER.

Specification of Letters Patent.

Patented July 17, 1906.

Application filed June 20, 1903. Serial Nn. 162.311.

1'0 (til [Ii/M)!!! it Iii/It]! (Inter/'11 Be it known that l,JonN K. Wnanca, a citizen of the United States, residing at Monroe,

in the county of Monroe and State of Michi.-' gan, have invented certain new and useful improvements in Fodder-Cutters, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates generally to foddercutters, and has particular reference to a combined cutter and blower-or pneumatic conveyor, the latter being adapted to receive the cut material and to elevate the same to a silo or other suitable receptacle.

The invention consists in the novel and simple construction of a fodder-cutter and in the peculiar arrangement and combination of its'various parts, as will be fully hereinafter set forth, and shown in the drawings, in which Figure 1 is a side elevation of a machine embodying my invention. Fig. 2 is a plan view thereof, the fan-casing being shown in section to illustrate its interior. Fig. 3 is aperspective view of the fan, the latterbeing shown partly in section; and Figs. 4 and 5 are views in elevationof the dicharge-section of the fancasing, showing the delivery-pipe in different positions in relation thereto. Fig. 6 is a side elevation of the fan-disk. Fig. 7 is a perspective view of one of the fan-plates. Fig. 8 is a section taken. on the line 8 8 of Fig. 1, showing a trough and a cutter for the material adjacent to the blade. Fig. 9 is a perspective view of the cutter-plate and one of the blades.

In the drawings thus briefly described, A

i represents a main supporting-frame, and B is the shaft journaled transversely thereof in suitable bearings C. The shaft at one end projects beyond its bearing and carries there on a b and-pulley I), while mounted centrally upon the shaft within the main supportingframc. is a fan-casing E. This casing as shown is substantially cylindrical, is provided with the usual air-inlet openings (1/ at each side, and carries suitable bearings F, through which the shaft extends, the fan-casing being loosely sleeved upon the shaft and adapted to be adjusted into different positions, as will be hereinafter set forth. I

G represents a discharge-section for the fan-case, extending upwardly from the periphery thereof and carrying near its top an annular flange b. Mounted upon the discharge-section and resting against the flange b as its base is a delivery-pipe l, the free or dischargeondoliwhich is adapted in the usual manner to be loosely secured to the silo or receptacle that is to be filled.

For the purpose of varying the angle of inclination of the delivery-pipe, which is de sirable for well-known reasons, 1 provide means for effecting the rotary adj nstment of the fancase about the drive-shaft upon which it is suspended. These means preferably consist, as shown, of arod (l, journaled in suitable bearings e on the base of the main frame, a worm f on the rod, and-a rack 9 upon the periphery of the casing above the worm, the arts engaging as shown. To produce the esired adjustment, the rod d is rotated by means of a suitable handle or crank It in a direction to throw the casing either into a forward or rearward position, as desired.

The fan for the casing I have shown in the form of a disk-shaped body J, reference being had particularly to Fig. 3, the peripheral' portion -of which is fashioned to form abutments K, extending in the plane of the disk and acting as backingsfor the fanblades L. The portion of the disk periphery immediately in advance of the abutments is cut away, as indicated at M, so that the maxi mum portion of a fan-blade will be exposed. Also a slot 7' is preferably formed in the disk intermediate the portions K and M to receive the lower end of the blade, as plainly indicated in the figure referred to.

laterally-projecting flanges 0, having inwardly-projecting upper ends 0, extend from the abutrnents, preferably from each side thereof, and to these flanges the blades L are rigidly secured by suitable bolts It will be obvious from the construction of the fan that the same,with the abutments and flanges, may be cast in a single piece, which materially reduces the cost of production. Furthermore, the fan-blades being inserted within the peripheral portion of the disk and backed by integral portions thereof a rigid and durable structure is produced and one in which there is but little liability of breakage.

To the fan wheel or disk just described areconnected the cutter-blades P. The connections may, if desired, be of the same construction as set forth in Patent No. 529,768, issued to me November 27, 1894. As this feature of the fodder-cutter constitutes no part of the present invention, no further description'will be necessary.

The disk is sleeved upon the shaft B within plished .I. arrange the pipe upon the tan-casing insuch manner that it may be readily shifted out of ahnement with the discharge-openmg,

.so that the material in the pipe may drop 1 through onto the ground. In the drawings l, have shown the delivery-pipe resting at its lower end upon the collar 1) of the dischargesection. A bell-crank lever Q forms an operative connection between the pipe and casing and serves as a means for shifting the .pipe. 'lhis lever, as shown, is fulcrumed at a point a to the discharge-section and has its short arm I) pivoted at c to the lower edge of' the pipe. When it is desired to move the delivery-pipe, the operator by actuating the lever shifts the pipe upwardly and laterallyul'itil it assumes the position indicated in dotted. lines in Fig. 4.

What I claim as my invention is 1. In a fodder-cutter, the combination of a fan-casing, and a fan rotatable therein, comprising a disk having portions of its periphery slightly reduced to form abutinents and having integral htterally-extended flan es at said reduced portions, and a series of tan-blades having interlocking slotted engagement with the disk immediately adjacent the abutlnents by which latter they are backed.

-2. In a fodder-cutter, the combination of a fan-casing and a fan rotatable therein, comprising a disk having portions of its periphery slightly reduced to form abutments, and a series of fanb lades having interlocking slotted engagement with the disk at said reduced portions and adjacent the abutments, by which latter they are backed.

3. In a fodder-cutter, the combination of a fan-casing and a fan rotatable therein, com prising a disk having portions of its periphery slightly reduced to form abutrnents and having laterally-extendcd flanges at said reduced portion, a series of fan-blades having interlocking slotted engagement with the disk immediately adjacent the abutments by which latter they are backed,.and means for securing said blades to said flanges.

' 4. In a fodder-cutter, the combination with a fan-casing, and a tan rotatable therein, comprising a disk having portions of its periphery slightly reduced to form abutments, and having laterally-extended flanges with inwardlyprojecting upper ends, said flanges being arranged adjacent said reduced portions, and'a series of' fan-blades having slotted engage' ment with said disk adjacentthe abutments, by which latter they are backed.

In testimony whereof I aflix my signature in. presence ol" two Witnesses.
